bos

Hello,
I have been trying to import a BOS file from a project that was exported in the same day from the same PC and now it says:
"Designed with a Subscription edition. Incompatible with Community edition"
I never had a subscription edition, I installed bonita last week so no update was made
I am using bonita 7.8.0

I'm following along with the getting started tutorial (Travel Requests) and I am at the part where it says to export the project from within bonita studio and then upload it as a resource in the portal. However when I go to resources in the coolbar and click add, it only allows me to upload zip files. Whats up with that?
